Operation Lumberjack saw Cleveland Police officers, some from the Special Constabulary, and a drugs dog visit 12 licensed premises across the Stockton area on Saturday night.

As a result, a 40-year-old man was arrested and charged for possession of a Class A substance. Three men aged 39, 37 and 27 were given street bail and are due to be interviewed on suspicion of possession of illegal substances.

The operation was not targeting specific licensed premises but people under the influence of illegal substances, sometimes in venues that attract families and children.

Sgt Daniel Trippett said: “This operation reflects the intelligence-led and proactive approach that we take in order to remove illegal substances from the streets.”
